          We are going to have to create some giga-mines to dig up all the materials to supply these places

          Plus a few giga-chemical extraction plants

            And if we want China to get rid of all their coal fired power stations then they get first dibs on the rare earth metals

              Meanwhile, here in 'Clean Green New Zealand' [laughter], the government has just announced it will tax fossil-fuel-burning vehicles, and provide cash bribes to slightly reduce the price of e-vehicles, so that, before you can say "greenwashing catches votes" we will be driving electric vehicles. It's also been reported that coal use for electricity generation has hit record levels, and the hydro lakes aren't as full as they 'should' be. No wind farms are being built. So where is all the extra, 'carbon-neutral' electricity going to come from? In rural NZ, it's wise to have a generator, to keep things going when the power-outages occur.

                I was under the impression that China was the largest supplier of rare earth metals , the extraction & processing of which cause huge amounts of pollution.

                But that pollution is "not here" – so that seems to make it OK.

                  "Greenwashing" is the right word

                  I wouldn't mind if the media just told the truth but our modern world isn't about what they do tell us

                  its about what they don't tell us

                      The alternative may be a trip back to a rural 1960 when you could pump your water out of the well by hand. Lights were paraffin and you walked to the end of the lane and paid to get your glass lead acid batteries charged by someone who had power. The Elsan got emptied into the midden.

                      Personally I would rather not.

                            So that battery factory is in such a cold location that it will take extra power to heat it, and the workforce has to travel long distances to get there. Allof the raw materials have further to go and the finished product also.

                              Yes makes me laugh ( a hollow one) when I see the green brigade banging on about green energy, emission free vehicles etc. I wish the media would really spell out the bigger picture, i.e. end to end pollution not just the end result.

                                  I'm not sure they will become redundant, because they could replace their liquid fuel pumps with a few of the many thousands of charging-points needed. Many rural garages gave up selling petrol & diesel a long time ago anyway, to concentrate on reapirs and sales, because the profit margin to the retailer is miniscule to the point of loss. Replacing the pumps, or the spots on which the pumps stood, with chargers would make sense….

                                  Assuming of course that in time the tax and wholesale cost on the electricity doesn't make that just as uneconomical….

                                    Why go to a charging station when you can charge at home or in the parking at your destination? These facilities are only needed on trunk roads for the long distance travellers.

                                      Sorry Bazyle but that idea is just not tenable for many thousands of people who like me could not re-charge a car at home, and in many cases may not be able to do so at their destinations either.

                                      What of all those who live in large blocks of flats, flats above town-centre shops; terraced houses built before motor-cars were common, or even invented? (As I do)

                                      In homes built without drives, on banks well above or below the road level?

                                      In trendy modern housing-estates built to resemble olde-worlde villages, with limited and scattered parking areas?The vague hope was that such pseudo-villages, like the Middle Farm estate (so-called ' Poundbury ' ) near Dorchester, in Dorset, would include or be very close to the places of employment etc. of residents, whom would appear assumed not to have lives outside of home and work. I think it was Government policy not so long ago to encourage such developments precisely to discourage car ownership.

                                      Such motorists have to take pot-luck on where they park; so will need ready access to convenient public charging-points just as most (though by no means all) presently have ready access to convenient filling-stations. And the time to wait in long, long queues.

                                      I think vast numbers of people will be forced off the roads by cost and practicality

                                      Electric cars are very, very expensive new, and not very likely to drop sufficiently in price for any but those who can also afford homes with private drives and chargers. Low-price second-hand battery-electric cars are likely to be too expensive for many because the low price is due to its costly batteries having about expired. Sooner or later the revenue lost by reduced liquid-fuel sales will likely force the government to tax car electricity, and that possibility may be why if you have a high-power charger at home it has to have its own meter.

                                      Practicality? Well, as above. If you cannot charge the car at home you are forced to use public chargers, and what takes 5 minutes now will take (by equivalence) 15 minutes or more, per car – and for less range, so something needing very careful thought.

                                      How do you pay, too? I have seen no charging-points with card-readers, apparently intending paying the unstated cost by "smart"-phone… assuming all motorists have or will want such a 'phone, good 'phone signals, and you don't mind the added 'phone contract and middle-man fees. It assumes the only charger for miles around on a dark cold wet night will be a) working, b) not in a radio shadow, c) compatible with your car and phone – the government making no attempt to enforce both easy payment and single-standard electrics.

                                      For example, from my home in the South of England to my caving-club in Yorkshire is 300 miles / 8 hours by petrol car, with about 100 miles on ordinary roads. To my brother near Glasgow is some 400miles, 8/9 hrs, about 80 miles non-motorway. These would become expeditions, especially in Winter when I would need prepare for far longer times and take warm clothing, hot drinks, and even a precautionary sleeping-bag. At least if I did not carry much with me, both are accessible by train, via Bristol – the club is close to a station on the Leeds-Settle-Carlisle line.

                                          Replacing cells in batteries is already a thing for cordless tools which use four cells and cost £60. Anybody who thinks that won't happen when there are 800 in a pack that costs several thousand £ is an idiot.

                                          As mentioned above, charging at home(or work!) won't be possible for a lot of users, so banks of chargers at convenient locations will be a necessity. That sounds very like a petrol station to me!

                                          The people who already run petrol stations would love to get rid of the expensive and short lived fuelling equipment; replacing the tanks, pumps etc with chargers is just the thing they're looking for.

                                              Nigel, Your letter has outlined very practical thinking on the future of the coming electric car era and matches a lot of my own thinking, and as you say a lot of peoples motoring lives will change, I live in a area where to get to the motorway system and major trunk roads there will be for the electric car some power sapping hills to climb, and with that will be the stress of the thought will I get to the next charging point.

                                              However I'm at that age that I won't have to bother about the coming change to motoring.

                                                The original Tesla S design was based around the concept of automated battery changes at fuel stations but the logistics of having spare fully charged packs about caused it to be abandoned. A total battery change on those cars took only a few minutes.
                                                There are independent Tesla repairers in the USA (only a few) that indeed will repair an old battery pack where one or two dud cells causes a brick section to fail and stop the whole pack working. At the mo' they just remove the dud cell rather than replacing it – to do with the way the battery management system works? – presumably a brand-new cell would also confuse on cell resistances?
                                                To keep manufacture costs down, the latest Tesla version will have the batteries built in as part of the structure of the vehicles, which will make access harder. Along with that they are starting to make the back and front frames out of single castings – yeah keeps their costs down but insurance rates will spike when such cars have to be scrapped from minor shunts and then shipped back for stripping and remanufacture.

                                                There area number of rivals coming on the scene so competition will bring prices down as will the scale of battery factories.

                                                On the recharging side that is improving well although prices to recharge on the road are leaping up stupidly to 70-80p per kWh unless signed up to some deal with overstay costs as high as £1 per min for folk who go off for coffee and leave the car when fully charged

                                                All new chargers UK are supposed to be fitted with some instant pay system, but it invariably costs more than being signed up to a particular charger system with monthly costs – can get expensive. Home charging for most journeys is the only practical solution, but gov lost revenue means they are looking at road pricing instead – more taxes.

                                                Personal view that anything that gets people off the road is a good thing so long as an effective public transport system is there. Getting lorries and vans off the road would be even better, but that's a tough nut to crack.

                                                Whatever may happen – if gov's target for all new electric cars by 2030 is even met – there will still be ICE cars on the roads for 10-12 year after that. 20yrs is enough time to sort out the infrastructure if the will was there. Except everyone believes that robotic vehicles will solve it, and I doubt they'll work in only 20years at current progress.

                                                  Interesting comment heard on the radio last week about insuring electric cars. Insurers are concerned about their high performance. Quite ordinary electric family saloons can accelerate from standing like a Ferrari! Rather likely this will cause accidents unless the electric car is set to launch at an ordinary rate.

                                                  I suspect having lots of electric cars on the road may alter the desire to own high-performance IC cars. Takes an IC supercar up to a mile to overtake an electric car in race mode. Only over long-distances does the IC do better. Not sure how chaps sat in a souped-up Porsch will react to being consistently left behind at the traffic lights by ordinary road users! Junctions, speed limits and busy public roads put their suck, squeeze, bang, blow engines at a disadvantage compared with electric. Batteries deliver amps almost immediately, power is transferred by the wiring and controller at close to the speed of light, and electric motors deliver instant high-torque straight to the wheels – no heavy clutch, gearbox, diff, axle, and propshaft to spin up as well. Electric cars can also rather simply compensate for each wheel having different road grip; without bothering the driver, controllers are able to optimise the power applied to each wheel independently during cornering, acceleration, and changing road conditions. An ordinary electric car delivers high-performance without needing a skilled driver.

                                                  For the same reasons IC super-cars will be outperformed at short distance track events. Thus they're in danger of becoming venue specialists like Formula 1 or Nascar, rather than desirable road-cars.

                                                  Sadly change always causes someone to lose out. I don't think electric cars will be half as much fun as IC for enthusiasts, because driving IC cars needs more skill. Of course there will be electric super-cars, but I doubt amateurs will be able create or improve them. High accelerations might also be made illegal on public road, I'm not sure 0 to 60 in under 2 seconds is a good thing when other people often jump the lights.

                                                  There's a lot that can done to improve the power output of IC engines, and enjoyable too but I suspect amateurs won't have the wherewithal needed to fit bigger batteries, or reprogram controllers, or improve sophisticated electric motors. Barnes Wallace considered himself lucky to have started work when an individual could design a whole aircraft on his own. At the end of his career even the simplest aircraft were team efforts, involving many different specialisms. So it is with most technologies: increasing complexity makes doing the same at home ever more difficult. But more people enjoy watching TV than repairing them!

                                                    DC Electric motors produce maximum torque at zero RPM. The current flowing through the windings generates a turning force. This will be dependent on the current and the radius of the rotor. The greater the current, the greater the turning force. At zero RPM all the current produces torque; there is no back EMF to reduce its output. Steam engines also, at rest, produce maximum torque, dependent on the phase of the valve gear.

                                                      Sub 2 secs was launched last week. I agree – stupid in the hands of nutters although i have to admit that the acceleration on my S ( a mere 4 seconds) is superb for getting past tractors. I hardly ever hoof it full chat – something you get over in the first few weeks and is just bragging rights and the latest incarnation of a production car speed limited to 200mph is also nonsense – going to be a serious mess on an autobahn soon.

                                                      Bet you guys can't guess the autobahn speed record and when it was made..
